SEOUL: South Korea’s antitrust regulator has designated Kim Bom-suk, known globally as Bom Kim, as the controlling figure of Coupang, a move that significantly expands regulatory oversight of the US-listed firm and its founder’s family.
The decision replaces Coupang Inc. with Kim as the group’s “same person” — a legal term under Korean antitrust law that identifies the effective controller of a business group and serves as the basis for monitoring related-party transactions and potential self-dealing.
This means the scope of related parties and affiliated companies is formally defined, triggering disclosure obligations on Kim and stricter rules on intra-group transactions, including limits on unfair support.
Under Korean antitrust law, even if an individual effectively controls a business group, regulators may designate a corporation — rather than the individual — as the “same person” if four conditions are met.
These are that the list of affiliates controlled by the individual is the same as that controlled by the person, that the controlling individual and their relatives do not hold stakes in domestic affiliates beyond the top entity, that relatives are not involved in management of domestic affiliates, and that there are no debt guarantees or financial transactions among domestic affiliates.
Why now?
Since 2021, when Coupang was first designated as a large business group with assets of 5 trillion won ($3.39 billion) or more, regulators had viewed Kim as exempt from "same person" designation.
That stance changed after an investigation tied to a data breach affecting about 33.7 million users. The probe uncovered signs of managerial involvement by Kim Yoo-seok, the founder’s younger brother and a Coupang vice president.
“We confirmed that Kim Yoo-seok exercised de facto influence over key business operations,” an FTC official said, noting his senior role, executive-level compensation and extensive involvement in logistics and delivery policy decisions.
Why does it matter?
The shift brings Kim and his family under stricter regulatory obligations. They must now disclose overseas affiliates in which they hold significant stakes and comply with tighter rules governing related-party transactions.
Authorities said any overseas affiliate in which Kim holds a 20 percent or greater stake will be subject to disclosure requirements, while transactions that confer undue benefits on related parties will face closer scrutiny.
How is Coupang responding?
Coupang has disputed the designation, arguing that its ownership structure prevents self-dealing and that its US listing subjects it to strict oversight by the US Securities and Exchange Commission.
“Kim’s brother is not an executive under Korean antitrust law and holds no equity in domestic affiliates,” the company said, adding it plans to challenge the decision through administrative litigation.
Why is this becoming a US-Korea issue?
The ruling comes amid rising tensions between Seoul and Washington over alleged discrimination against US-linked firms.
Coupang has spent over $1 million on US lobbying this year, engaging the White House and Congress. Recently, US lawmakers warned of the “systematic targeting” of companies such as Apple, Google, Meta and Coupang.
In response, South Korean lawmakers pushed back, urging respect for judicial sovereignty.
“No individual or corporation can stand above or outside its legal system,” they said.
What are the broader implications?
Some analysts warn the “same person” framework — rooted in Korea’s family-controlled conglomerate system — may not fit globally structured firms like Coupang.
Critics say it could undermine regulatory predictability, discourage foreign investment and trigger further investor disputes.
Concerns are already emerging among investors such as Greenoaks Capital and Altimeter Capital, which have pursued legal action tied to the earlier data breach. Coupang’s stock has fallen about 30 percent since the breach disclosure, closing near $20 on Tuesday.
What else changed?
The decision was part of a broader update to Korea’s conglomerate designations.
Dunamu retained its status under revised rules, while Jungheung Construction shifted control following a leadership change.
The number of designated business groups rose to 102, with 3,538 affiliates, up from 92 groups and 3,301 a year earlier. New entrants include Kolmar Korea, Toss and Orion. - The Korea Herald/ANN
